I've never had a problem getting a signal most anywhere I've traveled. Typically, when I'm away with some friends, it is my phone that has a signal while they (on Sprint or Verizon) are dropping calls and getting very poor signals. Also, when I go to Europe or Asia, I can purchase a pre-paid SIM at the airport and simply use my phone wherever I am without paying roaming charges.
If I didn't get good service, I would change carriers, which I did when I dropped Sprint after only 8 months. I've been with T-Mobile over 2 years now and have no plans to change.
